Troubleshooting

Die grinder not starting or low power

Check air hose connection for leaks, ensure air pressure is at 90 PSI, and verify the air inlet is not obstructed. Lubricate the tool with air tool oil.

Sanding disc not staying attached

Ensure the disc is fully screwed onto the backing pad arbor. Check that the backing pad arbor is securely tightened in the die grinder's collet.

Excessive vibration during operation

Verify that the sanding disc is centered on the backing pad and securely attached. Ensure the die grinder's collet is properly tightened.

Overheating of the tool

Ensure adequate air supply (4.5 CFM minimum). Do not force the tool; allow the speed to do the work. Take breaks to prevent overheating.
